Abstract

SE DESCRIBE UNA PALETA 6 PARA TURBINAS, CUYOS PERFILES EN P SE CONFIGURAN DE MANERA DIFERENTE PARA ADAPTARSE A LA SITUACION Y A LA VELOCIDAD DE CORRIENTE MODIFICABLE RADIALMENTE. EL OBJETIVO ES LA REDUCCION DE LA PERDIDA DE PALETAS COMO CONSECUENCIA DE LA CONFIGURACION DE ESTAS A TRAVES DE LA CORRIENTE SECUNDARIA. PARA ELLO SE PROPONE QUE LOS PERFILES EN P{SUB,R} PROXIMOS AL BORDE PRESENTEN UN AUMENTO DEL RADIO DEL CANTO DELANTERO R{SUB,N}, DEL ANGULO {GA}N DE CUÑA Y/O DEL ESPESOR 10 ABSOLUTOS CON UN ESPESAMIENTO 11, CONFIGURADOS MECANICAMENTE DE ACUERDO CON LA CORRIENTE. PARA ELLO EL ESPESAMIENTO 11 DE LA PALETA 6 SE MODIFICA EN LA ZONA DEL LADO DE ASPIRACION Y DE PRESION EN INTENSIDAD Y POSICION ESPACIAL DEL TORBELLINO SECUNDARIO, QUE GUIA FINALMENTE A LA MEJORA DE LOS GRADOS DE RENDIMIENTO DE ETAPAS. CASOS DE UTILIZACION VENTAJOSOS SON LAS PALETAS DE ROTORES Y ESTATORES, DE COMPRESORES, TURBINAS, VENTILADORES Y BOMBAS.
